Authorities say Burry Stander, one of the world’s elite mountain bikers, died Thursday in a road accident in South Africa. He was 25.

According to CNN, Stander was on a training ride near his home in Shelley Beach, on South Africa’s southeastern coast, when he was reportedly struck and killed by a taxi van.

Reports say the taxi driver allegedly stopped after the accident until the arrival of the police. No arrest has been made at this stage,” police said in a statement.

NPR notes the close proximity of the tragic accident to Stander’s childhood home apparently allowed the Olympians family members to arrive at the scene quickly.

“No parent should ever have to see his child lying on a tarred road after an accident, knowing that there is absolutely nothing he can do to save his life,” said his father, Charles Stander, in a statement released Friday. “It is definitely the worst moment of my life. Words cannot even begin to describe how one feels when it happens. It was terrible.”

Stander’s death has also sent shockwaves through the cycling community, with many members taking to Twitter to offer their condolences.
